socketcall (2)

int socketcall(int call, unsigned long *args);

socketcall() is a common kernel entry point for the socket system calls. call determines which socket function to invoke. args points to a block containing the actual arguments, which are passed through to the appropriate call.

User programs should call the appropriate functions by their usual names. Only standard library implementors and kernel hackers need to know about socketcall().

This call is specific to Linux, and should not be used in programs intended to be portable.

On a some architectures–for example, x86-64 and ARM–there is no socketcall() system call; instead socket(2), accept(2), bind(2), and so on really are implemented as separate system calls.

accept(2), bind(2), connect(2), getpeername(2), getsockname(2), getsockopt(2), listen(2), recv(2), recvfrom(2), recvmsg(2), send(2), sendmsg(2), sendto(2), setsockopt(2), shutdown(2), socket(2), socketpair(2)
